I-aluminium diboride i-AlB2 powder

 I-1, Isetshenziswa njenge-semiconductor ye-semiconductor yokulungisa izinga lokushisa eliphezulu, okokusebenza kwe-doped, okokusebenza kweshubhu, izinto ze-cathode nezinto ezimunca izinga lokushisa eliphezulu lenuzi neutron.

I-2, Le alloy ekhethekile inokumelana okuhle kokugqoka, ukumelana nokushisa, ukumelana ne-oxidation, ukumelana nezinga lokushisa kunobudlelwano obuqondile.Ingasetshenziselwa i-ceramic yensimbi, i-coat-resistant coating, ukumelana nokushisa okuphezulu, i-crucible lining, ukugcwalisa kanye ne-anti-corrosion. fafaza imishini yamakhemikhali.Ingasetshenziswa futhi njengezinto ezingaphili eziqinile kakhulu.

3, ingangena esikhundleni seshidi lensimbi ye-silicon, ukonga amandla angaphezu kwama-50%.

4, ube nohlelo oluthile embonini yenuzi, amarokhethi amarokhethi, izinga lokushisa eliphezulu, ishubhu lokuvikela ugesi, izingxenye zezimoto nokunye ukukhiqiza.

I-Aluminium borate (i-AlB2) iwuhlobo lwenhlanganisela kanambambili eyakhiwe i-aluminium ne-boron.

Iqinile ngokubomvu ngokumpunga ngaphansi kwezinga lokushisa elivamile nokucindezela.Izinzile ku-dilute ebandayo

i-asidi, futhi ibole ku-hydrochloric acid eshisayo ne-nitric acid.Ingenye yalezi ezimbili

izinhlanganisela ze-aluminium ne-boron.Enye i-alb12, ngokuvamile ebizwa ngokuthi i-aluminium

i-borate.I-Alb12 iyikristalu emnyama ecwebezelayo ye-monoclinic enamandla adonsela phansi angu-2.55 (18 ℃).

Ayincibiliki emanzini, i-asidi ne-alkali.Ibola ku-nitric acid eshisayo futhi iyatholakala

ngokuncibilikisa i-boron trioxide, isulfure ne-aluminium ndawonye.

Ngokwesakhiwo, ama-athomu B akha ama-graphite flakes ane-athomu ye-Al phakathi kwawo, okuyinto kakhulu

efana nesakhiwo se-magnesium diboride.Ikristalu eyodwa ye-AlB2 ibonisa insimbi

conductivity eduze kwe-eksisi ngokuhambisana nendiza ene-hexagonal ye-substrate.I-Boron

izinhlanganisela ze-aluminium ziqiniswa yi-boron fiber noma i-boron fiber ene-coating yokuzivikela.

Okuqukethwe kwevolumu ye-boron fiber cishe ku-45% ~ 55%.Amandla adonsela phansi athile aphansi, aphezulu

izakhiwo zemishini.Amandla e-longitudinal tensile kanye ne-elastic modulus ye-unidirectional

Inhlanganisela ye-boron aluminium eqinisiwe icishe ibe ngu-1.2 ~ 1.7gpa kanye no-200 ~ 240gpa, ngokulandelana.

I-longitudinal ethize ye-elastic modulus namandla athile cishe izikhathi ezi-3 ~ 5 futhi

Izikhathi ezi-3 ~ 4 ze-titanium alloy duralumin ne-alloy steel, ngokulandelana.Isetshenziswe ku

ama-turbojet fan blades, izimoto ze-aerospace nezakhiwo zesathelayithi.Ukucindezela okushisayo

i-diffusion bonding isetshenziselwa ukukhiqiza amapuleti, amaphrofayili kanye nezingxenye eziyinkimbinkimbi

amajamo, kanye nendlela yokusakaza eqhubekayo ingasetshenziswa futhi ukwenza amaphrofayili ahlukahlukene.
